Dictionary Example

This is an example of building a module that includes a dictionary in CMake. Instead of using the ROOT suggested flags, we will manually add threading via find_package, which is the only important flag in the list on most systems.

examples/root-dict/CMakeLists.txt

import:'main', lang:'cmake'

Supporting files

This is just a simple-as-possible class definition, with one method:

examples/root-dict/DictExample.cxx

import, lang:'c_cpp'

examples/root-dict/DictExample.h

import, lang:'c_cpp'

We need a LinkDef.h, as well.

examples/root-dict/DictLinkDef.h

import, lang:'c_cpp'

Testing it

This is an example of a macro that tests the correct generation from the files listed above.

examples/root-dict/CheckLoad.C

import, lang:'c_cpp'
